发布时间 2023-03-22 21:08:58作者: edata

添加对话框,修改调用对话框的命令参数

命令参数需要添加 ACRX_CMD_USEPICKSET | ACRX_CMD_REDRAW

ACED_ARXCOMMAND_ENTRY_AUTO(CArxProject1App, ArxProject1, mydlg, mydlg, ACRX_CMD_TRANSPARENT | ACRX_CMD_USEPICKSET | ACRX_CMD_REDRAW, NULL)

添加夹点亮显

主要使用acedSSSetFirst设置亮显， acedUpdateDisplay更新显示。

void CMydlg::OnBnClickedButton1()
{
	// TODO: 在此添加控件通知处理程序代码
	BeginEditorCommand();
	ads_name ss;
	if(RTNORM == acedSSGet(_T("L"),NULL,NULL,NULL,ss))
	{
		acedSSSetFirst(ss,NULL);		
		acedUpdateDisplay(); //更新显示
		acedSSFree(ss);
	}	
	CompleteEditorCommand();
}

.net例子

net添加命令

namespace ClassLibrary1
{
    public class Class1
    {
        [CommandMethod("mydlg",CommandFlags.UsePickSet|CommandFlags.Redraw|CommandFlags.Transparent)]
        public void ShowModalDialog()
        {
            using (Form1 form = new Form1())
            {
                Application.ShowModalDialog(form);
                
            }
        }
    }
}

按钮消息

 private void button1_Click(object sender, EventArgs e)
        {
            Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
            using (EditorUserInteraction edUsrInt = ed.StartUserInteraction(this))
            {
                var res = ed.SelectLast();
                if(res.Status == PromptStatus.OK)
                {
                    ed.SetImpliedSelection(res.Value);
                    ed.UpdateScreen();
                }
                
                edUsrInt.End();
                this.Focus();
            }
        }
